When are you due for a res change? She’s definitely asking for Calcium

Tomorrow for a change, ok I'll add some into this change. Thanks

Definitely, Add it first and let it sit at least 15 minutes before adding your base, I’ve had a issue with calcium dropping out of my mix when switching to DWC.

Ok, thanks mate.

For future reference - this wasn’t calcium deficiency. Necrotic lesions from Ca def have pronounced dark brown perimeters. These didn’t and the interveinal fading of older leaves points to a different diagnosis.

This was classic Mg def - and Epsom salt is the correct treatment - 1/2 to 1 g/gal added to reservoir or 1 to 2 g/quart for foliar.
